There are 360 smokers in group of 400 smokers began smoking before they reached their 21st birthday.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Approximately 9 out of 10 smokers began smoking before the age of 21.

Now,

Let number of smokers in group of 400 = x

Since, approximately 9 out of 10 smokers began smoking before the age of 21.

Hence, Number of smokers in group of 400 is,

⇒ 9 / 10 = x / 400

Solve for x as;

⇒ 9 × 400 / 10 = x

⇒ 9 × 40 = x

⇒ x = 360

Thus, There are 360 smokers started before they reached their 21st birthday.

Answer:

Package 10−pack of 2.3 ounce bars has the better price per bar

Step-by-step explanation:

Case 1) Package 10−pack of 2.3 ounce bars Cost ($) 17.35

Cost of Package 10−pack of 2.3 ounce bars = 17.35

Cost of Package 1−pack of 1 ounce bars = [tex]\frac{17.35}{10 \times 2.3}[/tex]

                                                                   = [tex]0.7543[/tex]

2)  12−pack of 1.6 ounce bars Cost ($)16.97

Cost of Package 12−pack of 1.6 ounce bars = 16.97

Cost of Package 1−pack of 1 ounce bars = [tex]\frac{16.97}{12 \times 1.6}[/tex]

                                                                   = [tex]0.8838[/tex]

Hence  Package 10−pack of 2.3 ounce bars has the better price per bar

Answer:

(B) 6h; $180

Step-by-step explanation:

Let h represents the number of hour.

Given,

Payment for an hour = $ 6,

So, the payment for h hours = 6h dollars,

Where, h is a variable.

Thus, the required variable representation is 6h.

If h = 30,

Thus, the total payment for 30 hours

= 6 ( 30 )

= $ 180

Hence, option B is correct.

The final sales price of the dress is a fraction 12/25 of the original price after successive discounts of 20% and 40%.

To determine the final sales price of the dress after multiple discounts, we can apply each discount successively. Let's assume the original price of the dress is $10, as mentioned in the premise, although this might be a typo or an example figure since a dress would typically cost more.

First discount: 20% off the original price, which is 0.20 x 10 = $2. So the new price after the first discount is $10 - $2 = $8.

Second discount: An additional 40% off on the already reduced price of $8. The additional discount is 0.40 x 8 = $3.20. Therefore, the final sales price after the second discount is $8 - $3.20 = $4.80.

To find the fraction of the original price that the final sales price represents, we divide the final price by the original price: $4.80 / $10 = 0.48. Thus, the fraction of the original price is [tex]\frac{48}{100}[/tex] or 24/50 after simplification, which further simplifies to  12/25

Answer:

a) Expression 1 = 29.833

b) (5+4) * 2 + 6 -2 * 2 - 1

Step-by-step explanation:

In expression 1 we have to know that the order to solve operations is:

First parenthesis, then multiplication and division and then addition and subtraction.

So we have the expression:

6*7-3/2*9+4/3

We first solve multiplications and divisions:

42-1.5*9+1.34

42-13.5+1.34 = 29.84

b) The parenthesis is the operation that goes first so if we insert the parenthesis in 5+4 we will get the next result:

(5+4) * 2 + 6 - 2 * 2 - 1

We have to solve parenthesis first, then multiplication and division and then addition and subtraction:

(9) * 2 + 6 - 4 - 1

18+6-4-1 = 19

We get the number 19.

The x- and y-intercepts are (8, 0) and (0, -2), respectively. and the graph is attached

From the question, we have the following parameters that can be used in our computation:

y = 1/4x - 2

To find the x-intercept, set y to 0 and solve for x:

0 = 1/4x -2

1/4x = 2

x = 8

So the x-intercept is (8, 0).

To find the y-intercept, set x to 0 and solve for y:

y = 1/4 * 0 - 2

y = -2

So the y-intercept is (0, -2).

The points A, B, C cannot be both collinear and form an equilateral triangle simultaneously. This is proven by applying the Pythagorean theorem and trigonometry laws for triangles, which show that the distances and angles do not match the requirements for an equilateral triangle if the points are collinear (on a straight line).

Given that points A,B,C are collinear and you've stated a variety of scenarios about the positioning of these points. Combining all these restrictions, however, leads to a contradiction. An equilateral triangle's points cannot all be collinear as you've mentioned in your last point. A collinear set of points exists on the same straight line. The points of an equilateral triangle do not fall on the same line. Therefore, it's impossible for points A,B,C to be collinear and also form an equilateral triangle ABC.

Applying the Pythagorean theorem to the positions of these points, we see that the distances on the sides of the triangle will not be equivalent if they are positioned in a straight line. Similarly, with the use of trigonometry laws for triangles, such as the ones for vector equations, the same result is found. The vector equations for collinear points lack the trigonometric components found in equilateral triangles.
